Around the time of the Cataclysm, certain irda underwent a
transformation, becoming closely linked with the sea. These irda
became the first of the yrasda, an irda-like race, whose members
could transform themselves into one of three different sea creatures.
Why these irda voluntarily underwent such changes is unknown,
although some sages speculate that they were sea-faring
irda who broke from their people to live permanently on and in
the sea.
Like irda, yrasda are shapeshifters, though each sub-race specializes
in a single animal form, and can assume no other.
Aphelka may take the form of squid, thanic may become a vicious
and disgusting carp-like fish, and ushama can transform
into killer whales (orca).
In their humanoid forms, yrasda look much like standard irda,
with a slender build, silver eyes, and drooping eyelids. Thanic
tend to have skin coloration of a deep sea green, while ushama
have midnight blue skin, and aphelka can have any tone in between.
They are graceful and possess beautiful voices, but are not as
peaceful as their irda antecedents. Aphelka are generally harmless,
though they will fight to defend themselves. Thanic are vicious
and aggressive predators, while ushama kill only what they
need to eat.

The above is taken from DLR2: Taladas - The Minotaurs. Has anyone used Yrasda in your campaigns? It seems they are found in all the oceans between Ansalon and Taladas so they need not be limited to Taldaas based campaigns. Do conversions exist to other editions?

I don't have DLR1 Otherlands with me right now, but it seems unlikely that they would have been covered there and then also included in DLR2 The Minotaurs. I would say that the Yrasda are most likely found in the Otherlands region though since this shapeshifting race could probably be found in most aquatic settings of the Dragonlance campaign world.
